Metal fume fever

Investigation of near infrared reflectance by tuning the shape of SnO2 nanoparticles

“…Other reported inorganic pigments, such as a white pigment (e.g. TiO 2 ) coated with another non-NIR absorbing pigment [2], polyolefin compositions containing a black colored pigment such as chromium-iron oxide [3], manganese vanadium oxide pigments such as Mn 2 V 2 O 7 , alkaline earth manganese oxides and bismuth manganese oxides [4]. But there is a little report on the property of pigment containing SnO 2 .…”

Near Infrared Reflectance Properties of Metal Oxide Nanoparticles

“…Solid solutions having corundum−hematite crystal structure were found to possess high NIR reflectance and these materials serve as coloring pigments in camouflage paints . The other reported inorganic pigments include (i) composites consisting of a coloring agent and a white pigment (e.g., TiO 2 ) coated with another non-NIR absorbing pigment, (ii) pigments based on rare earth manganese oxides, (RE x Mn)O y (RE = Y, Ca, Ce, Pr, Nd, and Sm) with an IR reflectivity ≥50%, (iii) metal coated particles and pigments useful in applications such as fabrics, paints, and visual camouflage, (iv) polyolefin compositions containing a black-colored pigment such as chromium−iron oxide, (v) bismuth manganese oxide pigments that can be used as additives in plastics and paints, (vi) Cr 2 O 3 −Fe 2 O 3 mixtures along with additives in a polymer with an IR reflectance of about 68%, (vii) pigments such as titanium dioxide, iron oxide, and chromium oxide with an effective size range from 1 to 8 μm, (vii) zirconium dioxide modified by silicon dioxide, and (viii) manganese vanadium oxide pigments such as Mn 2 V 2 O 7 , alkaline earth manganese oxides and bismuth manganese oxides . A few companies market NIR reflective pigments (e.g., V-799 Cool Colors Black marketed by Ferro Corporation).…”

The Lung in Metal Fume Fever

“…Although chills and myalgia are the most common symptoms reported, cough is described frequently, frank dyspnea is reported less often. 11,[26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44] The largest published cohort study of metal fume fever is that of Turner and Thompson, 26 who carried out a study of zinc oxide exposed workers in the 1920s under the aegis of the United States Public Health Service. Their study included 22 brass foundries employing 340 men.…”

“…In general, pulmonary auscultation in metal fume fever is unremarkable, although rales are sometimes observed. 11,[30][31][32][33]36,38,40,43 Chest radiographic examination is typically normal, but may reveal evanescent changes suggesting pulmonary edema. In one relatively large series, 5 of 43 cases of zinc-related metal fume fever from a shipyard welding exposure had radiographic abnormalities.…”
